Re-training tesseract 4.0.0-beta.1 - ocr

I am trying to do number plate recognition using teseract 4.0.0-beta.1. In the github page of tesseract, I found tesseract 4.0 training tutorial for different languages. But, I don't understand how to retrain this network for my use case. I searched for different blogs regarding retraining tesseract, but, was not able to find any. Can someone suggest me some blogs which explain the retraining portion of tesseract 4.0.0-beta.1 for different use cases?

How to implement labelImg function on the web browser

i am using labelImg tool for a graphical image annotation.
But for our education site, we would like to add this function of a graphical image annotation like labelImg into our web service.
https://github.com/tzutalin/labelImg
So Can we make labelling tool for data preparation for training on our website as one of function of data training?
Anyone have any idea concerned with this?
Ryan.
Labelimg is a desktop app that uses Qt for its UI. There exists solutions to run Qt in a Browser. See for example the solutions for Running Qt over the Web.
Otherwise I would recommend to explore other web-based tools for image annotation, e.g., the Computer Vision Annotation Tool (CVAT).
I hope you succeed in your endeavor.

Face detection demo using Siamese Network

I have learned the overview and functionality of Siamese network as it is One Shot Learning, I have tried some link from web which can give the demo of face detection using Siamese.
But I am not able to find any demo in which all the steps like training dataset, verification and testing steps are there. Can anyone have any reference link in which I can just detect the face from camera and comapre it with my Training dataset and that functionality I want using Siamese whether it is using tensorflow or keras.
Here is an example what you are looking for. The author has explained very nicely with python script, to find the similarity between ships and ice-berg, which can be easily expandable to any other application.

Understanding Caffe code for open source development

I am trying to understand caffe code code (both the C++ and the GPU part) as I want to start contributing to it but I am having a hard time since I could not find a documentation and I do not know what modules to read first. It would be very helpful if someone can give me some directions as to how to proceed and what tools should I use for development.

How to detect pitch on windows phone?

I know this is a rather general question, and apologies - I just can't find a start to this question anywhere. I'm currently building an app at a hackathon that will take voice/piano melody and decipher its pitch. I have found several javascript libraries that only work on servers, and do not work at all on WP.
I know a tuner can be done as I've seen several guitar tuner-type apps on the store, but I have no understanding of how to achieve the same result (and neither do the Microsoft representatives present) although I was suggested to look at FFT.
Again, I apologize for the general nature of this question. I would provide more information if I had it. Thanks.

Does anyone know of any good open source Geodjango apps to dig through?

I'm looking to build a small GIS in my spare time and have been digging into Geodjango.
I've been trying to find examples of open source Geodjango projects to look through, but I have had little luck, so here I am. I've been through most of the tutorials I could find, but they all seem to stop at the same point and I'm curious to look into some more complicated real-world code.
Anyone know if/where I can find some? Anything will suffice, but stuff using the Google Earth API as opposed to Open Layers would be ideal.
everyblock.com recently released their source code for their GeoDjango-based site. I've been digging through it - it's an interesting case study. It includes the public-facing site, a JSON API and some back-end data aggregation and map-generating code. Links and more info can be found at: http://www.everyblock.com/code/
I would recommend reading about what a GIS mapping stack is all about first. Once you understand where GeoDjango fits within this stack, there is a geodjango-basic-apps Google repository that gives some GeoDjango examples. The examples that you find online will swap certain portions of the stack (e.g. Open Layers for Google Maps API or MapServer for GeoServer) but the the design patterns and ideas are very similar if not the same in numerous cases.
